Write data rate twice that of read rate?

When using SuperDuper to backup to a sparse file on a local Firewire disk I noticed that the data write rate as observed by Activity Monitor is twice the data read activity. When copying files using other programs, e.g. Finder, the write rate is the same as the read rate.

Why is SuperDuper writing twice as much as needed?
